Left panel: Fermi-LAT TS map showing the γ-ray emission of Puppis A. The white circle marks the uniform disk used to fit Puppis A in 4FGL-DR3. The green contours mark the contour levels at 1% and 10% of the maximum of the eROSITA map (Mayer et al. 2022). Central panel: same as left panel but with radio VLA contours at 7% and 15% of the maximum of the VLA map. Right panel: residual TS map obtained by fitting the ROI (see text) using the disk template shown in the top panel. The red circle shows the uniform disk that models Puppis A (same as the white circle in the top panel), the red cross indicates the source 4FGL-J0822.8-4207 and the green crosses indicate the new sources needed to fit the gamma-ray excesses (Table 1).
